Sparrow King continued to fly SE across Nicaragua yesterday and likely passed over Lake Nicaragua on his way to Costa Rica. He has now crossed over to the Pacific Ocean side of Central America. So his preference for the west coast path to South America has already become apparent at this point.
Sparky has flown 516 km (321 mi) over the past two days. He roosted last night on a small, relatively flat offshore island about 16 km (10 miles) from the mainland. It is called Isla Del Cano, a Costa Rican National Park famous for its reefs, sea life and pre-Columbian stone spheres.
